morale-LIGHTING rma ctocx.

Application -led December The present invention relates to circuit closers, and more particularly to that type which are timed controlled.

An object of the present invention is to provide an automatic time controlled device for lighting day lights, night lights, and for extinguishing both lights at certain predetermined times for which the device may be set and which is adapted for use particu- Y larly in many places making it unnecessary to employ persons for operating the lights. Among such places where these automatic timed controlled circuit closers may be used are in factory halls, apartment houses, stores and the like.

Another object of this invention is to provide a relatively small, compact and economical circuit closer operated by clock -work or the like for closing and o ening circuits at different times, and whic may `be economically employed in the halls of apartment houses and the like to properly illuminate the same and prevent accident.

Another purpose of this invention'is to utilize the gears embodied in the structure of the device as electric contacts so as to obtain a direct closin of the circuit through the relatively mova le or shiftable parts of 1 lthe mechanism and eliminate a considerable amount of the mechanism usually employed in circuit closers of this type. v

A further object of the invention is to provide a time control circuit closer of this type which may be built into an ordinary clock mechanism and used in conjunction therewith for employing certain parts of the clock mechanism as parts of the circuit closer and utilize the dial face of the clock as a space for the independent dials used in the regulation and setting of the circuit closing mechanism.

The above and various other objects and advantages of this invention will in part be descmbed in, and in part be understood from the following detailed description of the present preferred embodiment of this invention, the same being illustrated in the accompanying drawings, wherein:

Fig. 4 is a sectional View similar to Fig; 2 but showing the contact gears in position for closlng one circuit and for maintaining the .other circuit open, and

lFlg. 5 is ra diagrammatic view of two circuits which may be utilized in conjunction with the circuit closer of this invention.

Referring to the drawings, wherein like parts are designated by similar numerals of reference throughout the several views', 10 designates the back of a casing and 11 designates a partition which is spaced from the back 11 a distance sutlicient. to accommodate any suitable clock Work or timing gears of ordlnary construction, and which are not shown. The front wall or face 12 of the caslng is spaced forwardly of the partition 11 to accommodate the major portion of the apparatus of this invention. The walls 11 and 12 carry the opposite end portions of a minute arbor or shaft 13 which is provided at its rear end with a drive pinion 14 adapted to be driven by the usual clock gearing and which is located between the back wall 10 and the partition 11. The shaft 13 also carries a pinion 15 which is disposed at the forward side of the partition 11 and with which meshes a gear wheel 16 carried upon an elongated electric non conducting pinion shaft 17 which is mounted upon the partition 11 and extends forwardly therefrom.

The minute shaft 13 carries a sleeve or hour shaft 18 thereon provided with agear wheel 19 meshing with the pinion shaft 17 and is driven by the latter to turn the hour shaft 18. The shafts 13v and 18 extends through the front wall 12 and are provided respectively with a minute hand 20 and an hour hand 21 adapted to traverse the usual hour designations on the face or dial of the Wall 12.

Three spindles 22, 23 and 24 are mounted through the walls 10, 11 and 12 of the casing and are equidistantly spaced apart at opposite sides of the pinion shaft 17 and a second pinion shaft 25 of similar electric non conducting material and disposed intermediate the spindles v23 and 24. The spindles, 22, 23 and 24 are mounted frictlonally in insulating bushings 26 itted'in the walls 10, 11 and 12 for supporting the spindles, and each spindle is provided upon its rear end with a knob or handle 27 by means of which the spindles may be manulll 22% neige?? ally turned to set the same. The forward ends of the spindles are each provided with 'a pointer 23 adapted to traverse dials 29 placed upon the outer face of the wall .12 and which are provided each with 24 designations of the twenty four hours of a day, and preferably numerically characterized by two sets of consecutive numberings from one to twelve.

Each spindle, 22, 23and 24 is provided witha laterally extending pin,30, and the pins 30 are spaced inwardly fr/om the front wall l2 in stepped relation fand are adapted to receive thereagainst circular' cams 3l, and 33 secured to the outer sides of electric conducting gear wheels 34, 35 and 36 mounted respectively for turning on the spindles 22, 23 and 24. The lower edges of the cams 31, 32 and 33 bear upon the upper or inner sides of the pins 3() and are rovided at the termination of the highest point of each cam with an abrupt shoulder 37 adapted to release the cam and its gear suddenly and to permit the outward thrust of the Aadjacent gear wheel, 34, 35 or 36, a distance equal to the depth of the shoulder 37 and under the tension of a Spring 38 arranged upon spindle behind each gear wheel 34, 35 and 36.

The gear wheels 34, 35 and 36 are arranged in overlapping relation so that they may be brought into surface contact with one another when permitted to slide upon their respective spindles, and so that the gear wheels may mesh with the adjacgut pinion shafts 1'7 and 25. As the pinion shaft 17 is driven from the pinion 15 of the minute shaft 13, the gear wheels 35, 34 and 36 are of sufficient size to make each a complete revolution every twenty four hours. The gear wheels 34, 35 and 36 provide the movable contacts of the device, and the spindles 22, 23 and 24 provide a ready means for conducting electric current through the device from various circuits. The present drawings show a wire 39 which leads to a generator 40 and which is connected to branch wires 41 and 42 provided respectively with lamps 43 and 44 therein, the circuit 41 being utilized as a day circuit while the circuit 42 may be utilized as a night circuit. The branch wires 4l and 42 are connected to the spindles 22 and 24 respectively while the middle or central wire 39 is connected to the spindle 23.

In operation, the ear wheel 34 is driven directly from the pinion shaft 17 and the latter also directly drives the gear wheel 35. The gear Wheel 35 rotates the second pinion shaft 25 and the latter drives the third gear wheel 36. The spindles 22, 23 and 24 are manually set respectively, according to the readings on the dials 29, at 5 p. m., 10 p. m. and 2 a. m. When 5 p. m. is reached the gear wheel 34 has revolved to that point where the shoulder 37 of the cam 30 registers with the pinland the spring 38 lforces the gear wheel 34 forward into contact with the gear wheel 35' as shown in Fig. 4 so as to close the circuit through the wires 39 and 41. i

.The gear wheel 35 is also revolving, and at the same time. is being forced backwardly by its cam 32 and thus a good contact is 'maintained between the gear wheels 34 and 35. These gear wheels are held `Jtogether until .10 p. m. when the shoulder 37 is brought into register with the pin 30 on the spindle 23, at which timethe .spring 33'snaps the .gear wheel 35 outwardly or forwardly away from the gear wheel 34, breaking the circuit. This extinguishes the day of main lights 43. The gear wheel 35, upon moving forwardly may come into Contact withthe gear wheel 36 unless the latter has been previously rojccted forwardly as shown in Fig. 4. (gear wheel 36 is forced backwardly by its cam 33 and the position of the cam 33 may be such as to eliect contact between the gear wheels 35 and 36 for a predetermined length of time, accordingto the settings of the spindles 23 and 24. Thus, an interval' may elapse wherein both of the circuits are broken as shown in Fig. 2, or where one of the circuits only is broken as shown in Fig. 4. l Various closing and opening of the circuits may be effected by adjustment of the spindles 22, 23 and 24 and the times of such openingand closing of the circuits may be positively regulated as the gear wheels 34, 35 and 36 are connected to move simultaneously4 and equally, and are revolved one complete turn in each twenty four hours.
